Forum Rules (Everyone Must Read!!!)

1] What you CAN NOT post.

You agree, through your use of this service, that you will not use this forum to post any material which is:
- abusive
- vulgar
- hateful
- harassing
- personal attacks
- obscene

You also may not:
- post images that are too large (max is 500*500px)
- post any copyrighted material unless the copyright is owned by you or cited properly.
- post in UPPER CASE, which is considered yelling
- post messages which insult the Armenians, Armenian culture, traditions, etc
- post racist or other intentionally insensitive material that insults or attacks another culture (including Turks)

The Ankap thread is excluded from the strict rules because that place is more relaxed and you can vent and engage in light insults and humor. Notice it's not a blank ticket, but just a place to vent. If you go into the Ankap thread, you enter at your own risk of being clowned on.
What you PROBABLY SHOULD NOT post...
Do not post information that you will regret putting out in public. This site comes up on Google, is cached, and all of that, so be aware of that as you post. Do not ask the staff to go through and delete things that you regret making available on the web for all to see because we will not do it. Think before you post!


2] Use descriptive subject lines & research your post. This means use the SEARCH.

This reduces the chances of double-posting and it also makes it easier for people to see what they do/don't want to read. Using the search function will identify existing threads on the topic so we do not have multiple threads on the same topic.

3] Keep the focus.

Each forum has a focus on a certain topic. Questions outside the scope of a certain forum will either be moved to the appropriate forum, closed, or simply be deleted. Please post your topic in the most appropriate forum. Users that keep doing this will be warned, then banned.

4] Behave as you would in a public location.

This forum is no different than a public place. Behave yourself and act like a decent human being (i.e. be respectful). If you're unable to do so, you're not welcome here and will be made to leave.

5] Respect the authority of moderators/admins.

Public discussions of moderator/admin actions are not allowed on the forum. It is also prohibited to protest moderator actions in titles, avatars, and signatures. If you don't like something that a moderator did, PM or email the moderator and try your best to resolve the problem or difference in private.

6] Promotion of sites or products is not permitted.

Advertisements are not allowed in this venue. No blatant advertising or solicitations of or for business is prohibited.
This includes, but not limited to, personal resumes and links to products or
services with which the poster is affiliated, whether or not a fee is charged
for the product or service. Spamming, in which a user posts the same message repeatedly, is also prohibited.

7] We retain the right to remove any posts and/or Members for any reason, without prior notice.


- PLEASE READ -

Members are welcome to read posts and though we encourage your active participation in the forum, it is not required. If you do participate by posting, however, we expect that on the whole you contribute something to the forum. This means that the bulk of your posts should not be in "fun" threads (e.g. Ankap, Keep & Kill, This or That, etc.). Further, while occasionally it is appropriate to simply voice your agreement or approval, not all of your posts should be of this variety: "LOL Member213!" "I agree."
If it is evident that a member is simply posting for the sake of posting, they will be removed.


8] These Rules & Guidelines may be amended at any time. (last update September 17, 2009)

If you believe an individual is repeatedly breaking the rules, please report to admin/moderator.

  • HM - Word's most famous amnesic dies

    Every time I teach (or even think about actually) this man and what happened to him at the hands of a moronic "surgeon" it makes me furious and very sad simultaneously. The article is kinder to Dr. Scovile than he deserves. He was unprecedented, unjustified, and incredibly reckless. This @sshole even went home and joked to his wife that he tried to suck out a man's epilepsy and sucked out his memory instead. Disgusting!

    HM's tragic life has helped shed much light on memory and the function of the hippocampus. He didn't remember the researchers he worked with, but after years of making the same drive to MIT, he recognized it and understood that studying him would help science and others.

    He knew his name. That much he could remember.
    He knew that his father’s family came from Thibodaux, La., and his mother was from Ireland, and he knew about the 1929 stock market crash and World War II and life in the 1940s.

    But he could remember almost nothing after that.

    In 1953, he underwent an experimental brain operation in Hartford to correct a seizure disorder, only to emerge from it fundamentally and irreparably changed. He developed a syndrome neurologists call profound amnesia. He had lost the ability to form new memories.

    For the next 55 years, each time he met a friend, each time he ate a meal, each time he walked in the woods, it was as if for the first time.

    And for those five decades, he was recognized as the most important patient in the history of brain science. As a participant in hundreds of studies, he helped scientists understand the biology of learning, memory and physical dexterity, as well as the fragile nature of human identity.
    ...

    At a time when neuroscience is growing exponentially, when students and money are pouring into laboratories around the world and researchers are mounting large-scale studies with powerful brain-imaging technology, it is easy to forget how rudimentary neuroscience was in the middle of the 20th century.

    When Mr. Molaison, at 9 years old, banged his head hard after being hit by a bicycle rider in his neighborhood near Hartford, scientists had no way to see inside his brain. They had no rigorous understanding of how complex functions like memory or learning functioned biologically. They could not explain why the boy had developed severe seizures after the accident, or even whether the blow to the head had anything do to with it.

    Eighteen years after that bicycle accident, Mr. Molaison arrived at the office of Dr. William Beecher Scoville, a neurosurgeon at Hartford Hospital. Mr. Molaison was blacking out frequently, had devastating convulsions and could no longer repair motors to earn a living.

    After exhausting other treatments, Dr. Scoville decided to surgically remove two finger-shaped slivers of tissue from Mr. Molaison’s brain. The seizures abated, but the procedure — especially cutting into the hippocampus, an area deep in the brain, about level with the ears — left the patient radically changed.

    Alarmed, Dr. Scoville consulted with a leading surgeon in Montreal, Dr. Wilder Penfield of McGill University, who with Dr. Brenda Milner, a psychologist, had reported on two other patients’ memory deficits.

    Soon Dr. Milner began taking the night train down from Canada to visit Mr. Molaison in Hartford, giving him a variety of memory tests. It was a collaboration that would forever alter scientists’ understanding of learning and memory.

    “He was a very gracious man, very patient, always willing to try these tasks I would give him,” Dr. Milner, a professor of cognitive neuroscience at the Montreal Neurological Institute and McGill University, said in a recent interview. “And yet every time I walked in the room, it was like we’d never met.”

    At the time, many scientists believed that memory was widely distributed throughout the brain and not dependent on any one neural organ or region. Brain lesions, either from surgery or accidents, altered people’s memory in ways that were not easily predictable. Even as Dr. Milner published her results, many researchers attributed H. M.’s deficits to other factors, like general trauma from his seizures or some unrecognized damage.

    “It was hard for people to believe that it was all due” to the excisions from the surgery, Dr. Milner said.

        I never met him. But reading this made me think of that movie 50 first dates. If there is a collection for flowers I am willing to donate.

          This story does reinforce my opinion of doctors.
